The "AI" versions of the movie stills are darker and "greener" or "bluer" in all cases in this article, which is NOT the case when you watch the movie. It's a mistake on the part of whoever put together the image comparisons.
The culprit here is that the non-AI screenshots are taken from presumably 1080p non-HDR sources, while all the AI screenshots are taken from presumably 4K HDR sources. The "AI" images are all displayed in the completely wrong color space -- the dark+green/blue is exactly what HDR content looks like when played on software that doesn't correctly support decoding and displaying HDR content.
It's a shame that the creator of the comparison images doesn't know enough image processing to understand that you can't grab stills from HDR content from a player that doesn't properly support HDR.
On the other hand, the state of HDR support is a mess right now in software players. Playing HDR content in common players like VLC, QuickTime, IINA, and Infuse will give you significantly different results between all of them. So I can't actually blame the creator of the images 100%, because there isn't even a documented, standardized way to compare HDR to non-HDR content side-by-side, as far as I know (hence why each player maps the colors differently).
It's not surprising. The usual quality metrics that video-encoder people use tend to be positively correlated with saturation (and in fairness, this is what people think is better 'quality').
